“…There are several in vitro studies that have evaluated the accuracy of MRZX in the presence of sodium hypochlorite irrigating solution and concluded that a dry or wet canal does not significantly affect the accuracy of MRZX [10,[16][17][18][19]. These findings were supported in detail with the results of the present investigation.…”

This ex vivo study aimed to measure the performance of an electronic apex locator (EAL) in the presence of sodium hypochlorite irrigants with different concentrations. Two EALs (Root ZX Mini and Locapex 6) were used to locate the apical foramen in 10 extracted single-rooted teeth in the presence of 0.5%, 2.5% and 5% sodium hypochlorite. Visual working lengths were also determined using #10 K-file under a microscope before the electronic measurements were made. The performance of both EALs was compared for the electronic working lengths determined under the different concentrations of sodium hypochlorite. A multiple-way ANOVA and PLSD Fisher’s test with an α risk fixed at 5% were conducted. There were no statistical differences in the working lengths determined by both EALs between the three groups with different concentrations of sodium hypochlorite and their visual control measurements. When a ± 0.5 mm margin was applied, the Root ZX Mini and the Locapex 6 presented 88% and 83% accuracy, respectively. Sodium hypochlorite concentration in irrigants does not affect the accuracy and reliability of either the Root ZX Mini or the Locapex 6. Electronic apex locators are reliable with any concentration of sodium hypochlorite irrigants.

“…The electrical resistance of the EAL and the resistance between the file and the oral mucosa when they become equal results in a beeping noise, which indicates that the apex has been reached. There is a high correlation between the electronic and direct root canal length measurements [16].…”

“…Electronic Apex locators are widely studied, however, a recent systematic review concluded that more in vivo or in vitro studies should be performed to obtain more precise and valid data on the accuracy of different generations of EALs (Nasiri et al 2022).…”

Objective: The aim of this study was to determine the correlation between the distance from the file tip to the apical foramen and the readings on displays of two Electronic Apex Locators. Methodology: 46 human teeth were accessed, and electronic measurements were obtained at the display levels: 2.0; 1.5; 1.0; 0.5 and “apex”, these electronic measurements were repeated. Results: At the 0.0 and 0.5 display numbers, there was an accurate detection of the apical foramen: 93.5% for the Root ZX II and 93.5% for the RomiApex A-15 (± 0.5 mm). Analysis of variance (ANOVA) revealed that the accuracies of the two devices did not differ (p>0.05). At 2.0, 1.5 and 1.0, the accuracy was low and there was a significant difference in the accuracy of booth devices (p=0.000). When evaluating repetition of measurements, there was a high level of reproducibility (the ICCs ranged between 1.000 and 0.992 for the Root ZX II and between 1.000 and 0.989 for the RomiApex A-15) in all evaluated display’s levels. Conclusions: Both devices displayed high accuracy and reproducibility at the 0.0 and 0.5 display numbers.

“…8 In another recent review study, Nasiri and Wrbas stated that electronic apex locators, regardless of their generation, prove to be beneficial for patients suffering from gag reflex or those who cannot endure X-ray film or sensor. 9 Another challenge for clinicians in this pandemic is the cyclic vomiting syndrome (CVS); it was first recognized in pediatrics; however, it is now confirmed that adults can also suffer from CVS. The exact etiology of CVS is unknown; nonetheless, stress, anxiety, and lack of sleep are all linked to CVS, which causes severe nausea and vomiting for hours.…”
